Alan Evans became violently ill after taking only a few bites of the egg McMuffin. When he noticed the mold in his sandwich, he immediately stopped eating it. However, he began to feel sick within a few hours. He was bedridden with a horrible case of food poisoning for five days after the fact.

"I just couldn't stop being sick or going to the toilet. I've got really bad pains in my stomach. Now even looking at McDonald's on television just makes me feel sick. I should never have contemplated eating a green egg. I just can't believe I ate it."

Evans went on to say that he was angry with the McDonald's staff's response to the incident. While they offered him a free meal (which he will undoubtedly decline after the food poisoning), they did not offer his money back. A spokesperson for McDonald's said that the company is investigating the situation. In a statement, he said:

"The eggs used in our McMuffins are made with real, free-range eggs that are freshly cracked in the restaurant every day by our crew."

Better take a look inside your egg McMuffin before biting into it from now on!
